SUSAN LOUISE ARNOLD, OF OTTAWA, ILLINOIS.

ADJUSTABLE WALKER.

To all whom it may concern:

Be it known that I, SUSAN LOUISE Are NOLD; acitizen of the UnitedStates, residing at Ottawa in the county of Lasalle and State ofIllinois, have invented certain new and useful Improvements inAdjustable lValkers of which the following is a specifi cation.

My invention relates to an adjustable walker.

My invention is designed for the service of those who through sicknessor other cause, are deficient in the necessary strength or have lost theability to walk.

My invention comprises seating, supporting and adjustable barsassociated with the portable structure adapted to support or aid in thesupport of the user either sitting, standing or walking.

In the drawings, Figure 1 is a perspective view of the device showing ahinged side in opened position with relation to the main frame. Fig. 2is a top view of the device; Fig.3 is a front end view of the walker;Fig. 4: is a side view at theleft of the device; Fig. 5 is a rear endview of the device; Fig. 6 is a side view at the right of the device;Fig. 7 is a sectional View showing a seat portion and adjustable backassociated with the seat; Fig. 8 is a perspective view of a rod supportassociated with the framework and adapted to support the adjustableback; Fig. 9 is a commode; Fig. 10 is a perspective view showing themeans for uniting the adjustable bars to upright sections of theframework; Fig. 11 is a perspective view in detail of a ratchet bar anda cam lock therefor associated with the framework; Fig. 12 is aperspective view of a slotted angle plate adapted to work in connectionwith ratchet bar shown in Fig. 11; Fig. 13 is a detail view showingmeans of connecting the adjustable bars with vertical frame parts; andFig. la is a detail view showing means of locking the gate portion inconnection with the framework.

In the drawings, 2 indicates corner posts which may be of any sizedesired. The corner posts may be connected in any suitable manner toproduce a rectangular frame structure of the nature disclosed in thedrawings, but I have shown the posts at the front end of the deviceconnected by means of cross frame pieces 3, which may be permanent incharacter. The rear posts are Specification of Letters Patent.

connected by means of cross frame pieces 4 which may likewise bepermanent in character. The front and rear posts at the left side of theframework may be connected by means of a bar as 5 which may be of apermanent character. The right hand side I have shown built insubstantially gate form and comprising uprights as 6 and 7 connected attheir lower ends by means of frame piece 8. To this frame is permanentlyconnected horizontal frame pieces 9 and 10, and the outer ends of saidframe pieces are connected by means of vertical bar 11. This frame isadapted to be hinged to the main framework as at 12.

13 is a box formation or commode built in at the rear end of the mainstructure. the top of which may be of the usual stool formation and maybe provided with a suitable upholstered cover. The entrance to thecommode is provided at the back. as shown in Fig. 5, into which a dooras 14 is adapted to be fitted, and the same may be provided with asuitable lock.

15 is a sanitary pan which may be of any suitable form desired and maybe placed within thecommode through the opening at the rear of box 13.

16 is an adjustable back which may be upholstered as shown. The lowerportion of the back is pivoted upon rod 17 supported in connection withrear uprights 2 by passing through perforations in the frame-parts ofthe back. Adjustable means are provided for changing at will theposition thereof, comprising angle plates as 18 attached to the insidefaces of the rear uprights 2 and each provided with a slot as 19.

20 are ratchet bars adapted to be pivoted to the respective sides of theadjustable back and adapted to be carried through slots 19 in angleplates 18. The outer ends of ratchet bars 20 are of greater width thanthe main body thereof and wider than the length of slot 19, whichproportioning of the ratchet bars prevents the same from being whollywithdrawn from angle plates 18.

21 (see Fig. 11) is a cam adapted to be pivoted to angle plate 18, therebeing one of such cams at each side of the adjustable back supported insuch relation to the ratchet bars 20 that as the ratchet bars are inengagement with the edge of slot 19 in any desired position in angleplate 18, the cam may be turned to hold the bars firmly in place and maybe moved to release the bars so that adjustment of the back may be hadat will.

I have provided adjustable bars in con- 5 nection with the right andleft hand sides of the general frame structure to afford support of theuser either in standing, resting position or in walking position. Thebars on the left hand side are designated respectively 22 and 23 andthey are detachably hand side of the structure, I provide a plurality ofperforations as 2' in vertical corner posts 2 and in connection with anintermediate permanent vertical frame piece 25. (hi the right hand sideof the structure and 5 in connection with the openable gate portion, Ihave provided a pair of bars '26 adapted to be seated upon upright framepieces 27 in the manner shown in Fig. 13, the ends of said bars beingconnected on the outside of vertical frame pieces 27 by means of cleats2S. 26 being connected. in the manner described and shown, they aremovable together up or down upon vertical frame pieces 2'7. A slot isprovided in each end of the parallel bars 26 adapted to receive theupright frame pieces 27 and be locked in position by bolts as 2a (seeFig.

A plurality of perforations c is provided in the vertical upright pieces27.

Metal strips or washers, as 29 in connection with bars 26, and 30 inconnection with vertical frame pieces 27 may be provided, the washer orstrip 29 to be threaded to receive the threaded end of bolt 22 and themetal strip of washer 30 serving as a wearing plate.

31 is a table and 32 a foot board. Said table and foot board may beprovided with cleats overlapping the edges of the frame parts and arereadily detachable so that they may be placed in position or removed atwill.

33 are brackets fixed to one of the rear corner posts 2 serving as asupport for the forward end of the gate formed right side portion of theframe structure.

34 are hoolis on one of the corner posts 2 and 35 are eyes (one of whichis shown in Fig. ll) upon the gate adapted to lock the latter in closedposition.

36 is a shelf upon which the user may lean as a rest while standing and37 is a brace which extends from the shelf to the horizontal bar at theleft of the frame structure.

This device is intended as an aid in assisting a person in walking. Thedevice as constructed with the openable side accommodates the placing ofthe structure adjacent a bed, making a convenient entrance from the bedpossible. The seat and back are disposed relatively and the latter madeadjust able to accommodate a comfortable sitting place for the user. Thecommode feature adds to the usefulness and convenience of the device.The adjustable bars accommodate adjustments for the most convenientdesired support for the user in standing or in walking. The removabletable and foot board are conveniences of evident value.

I have shown one form of embodiment of my invention but desire to coverby my patent all forms of walkers without regard to proportion of partsor particular arrangement thereof that may legitimately fall within thescope of my invention.

What I claim is:

In an adjustable walker, a movable frame structure comprising permanentend sections, and -a side section and openable side sections hinged tothe structure, a seat por tion within the structure and an adjustableback associated with the frame and in juxtaposition to the seat,adjustable bars forming a part of the permanent side portion, one ofsaid bars extending only a portion of the length of said side, leavingan open space convenient for the passing of articles therethrough, anadjustable frame comprising a plurality of longitudinal bars upon thehinged section, said frame extending only a portion of the length ofsaid hinged seetion, leaving an open space for the convenience ofpassing articles therethrough and means for securing the bars in theirseveral adjustable positions substantially as described.

In testimony whereof I have affixed my signature in presence of twowitnesses.
